sprintf_s downgrade possible ?

[PawelSokolowski]

Hi all,

I was not aware that VS2008 does not build NT 4.0 valid applications, and I
migrated from VS2003 to VS2008
Unfortunatelly one of my client still uses NT on about 200 computers, and
cannot upgrade to XP, they are simply too old.

While migrating I made about 1800 changes in code, and I don't really like
the idea of changing everything back.
Many of those changes were securing sprintf function.
sprintf(...) -sprintf_s(...)

Do you have some idea about compiling sprintf_s under VS2003 ???

I doule like to create a sprintf_s function, passing arguments to regular
sprintf.
Since it has variable list of arguments, I have a problem how to pass them.
I would appreciate any suggestions.


Regards
Pawel

Out of interest, what aspects prevent VS2008 built applications
running on NT4?

The CRT (and possibly MFC) depend on newer versions of Windows.
Building a win32 app form scratch without CRT and MFC should still work.

In addition to what others wrote, you may consider also StringCchPrintf
function:

http://msdn.microsoft.com/en-us/library/ms647541(VS.85).aspx

it is available in VS.NET 2003, too.

HTH,

You're welcome.

Sometimes simple solutions can do a good job :)
